Code Releases Activity

Use the controller name 'Greetings' consistently.

Browse source 
Moreover, there seems to be a bug in Rails 2.3.0: After editing the view file
apps/views/greetings/hello.html.erb in Vim, WEBrick ships the outdated content
from the backup file apps/views/greetings/hello.html.erb~ instead of the
intended content. Only when the 'tilde backup' file is not present, the browser
shows the correct contents (both Konqueror and Firefox; you can even add a
_different_ hello.html.erb~ to show completely different stuff).

This bug does not occur in Rails 2.2.2.
